(a) Any interested party desiring review of a determination issued under §§655.805 and 655.815, including judicial review, shall make a request for such an administrative hearing in writing to the Chief Administrative Law Judge at the address stated in the notice of determination. If such a request for an administrative hearing is timely filed, the Administrator's determination shall be inoperative unless and until the case is dismissed or the Administrative Law Judge issues an order affirming the decision.
(b) Interested parties may request a hearing in the following circumstances:
(1) The complainant or any other interested party may request a hearing where the Administrator determines, after investigation, that there is no basis for a finding that an employer has committed violation(s). In such a proceeding, the party requesting the hearing shall be the prosecuting party and the employer shall be the respondent; the Administrator may intervene as a party or appear as amicus curiae at any time in the proceeding, at the Administrator's discretion.
(2) The employer or any other interested party may request a hearing where the Administrator determines, after investigation, that the employer has committed violation(s). In such a proceeding, the Administrator shall be the prosecuting party and the employer shall be the respondent.
(c) No particular form is prescribed for any request for hearing permitted by this section. However, any such request shall:
(1) Be dated;
(2) Be typewritten or legibly written;
(3) Specify the issue or issues stated in the notice of determination giving rise to such request;
(4) State the specific reason or reasons why the party requesting the hearing believes such determination is in error;
(5) Be signed by the party making the request or by an authorized representative of such party; and
(6) Include the address at which such party or authorized representative desires to receive further communications relating thereto.
(d) The request for such hearing shall be received by the Chief Administrative Law Judge, at the address stated in the Administrator's notice of determination, no later than 15 calendar days after the date of the determination. An interested party which fails to meet this 15-day deadline for requesting a hearing may thereafter participate in the proceedings only by consent of the administrative law judge, either through intervention as a party pursuant to 29 CFR 18.10(b) through (d) or through participation as an amicus curiae pursuant to 29 CFR 18.12.
(e) The request may be filed in person, by facsimile transmission, by certified or regular mail, or by courier service. For the requesting party's protection, if the request is by mail, it should be by certified mail. If the request is by facsimile transmission, the original of the request, signed by the requestor or authorized representative, shall be filed within ten days.
(f) Copies of the request for a hearing shall be sent by the requestor to the Wage and Hour Division official who issued the Administrator's notice of determination, to the representative(s) of the Solicitor of Labor identified in the notice of determination, and to all known interested parties.
